# §654.409. Heating.

- (a) All living quarters and service rooms must be provided with properly installed, operable heating equipment capable of maintaining a temperature of at least 68 degrees Fahrenheit ( °F) if during the period of normal occupancy the temperature in such quarters falls below 68 °F.
- (b) Any stoves or other sources of heat utilizing combustible fuel must be installed and vented in such a manner as to prevent fire hazards and a dangerous concentration of gases. No portable heaters other than those operated by electricity may be provided. If a solid or liquid fuel stove is used in a room with wooden or other combustible flooring, there must be a concrete slab, insulated metal sheet, or other fireproof material on the floor under each stove, extending at least 18 inches beyond the perimeter of the base of the stove.
- (c) Any wall or ceiling within 18 inches of a solid or liquid fuel stove or a stovepipe must be of fireproof material. A vented metal collar must be installed around a stovepipe, or vent passing through a wall, ceiling, floor, or roof.
- (d) When a heating system has automatic controls, the controls must be of the type which cut off the fuel supply upon the failure or interruption of the flame or ignition, or whenever a predetermined safe temperature or pressure is exceeded.
